Grilled Vegetable Panini With Basil Pesto

For Panini:.

Heat a grill pan over medium-high heat. Drizzle the oil over the eggplant, zucchini, and onion slices, then sprinkle with salt and pepper.

Working in batches, grill the eggplant, zucchini, and onions until they are tender and grill marks appear, about 4 minutes per side.

Cool completely.

Cut each baguette into 6 pieces.

Working with one baguette piece at a time, slice in half and spread both sides with the pesto.

Working with the bottom slice of the baguette, stack 2 slices of eggplant, 2 slices zucchini, 1 slice onion, 1 slice tomato, 1 slice mozzarella, and 1 slice of roasted pepper.

Sprinkle with salt and pepper.

Place top half of baguette on top and continue with remaining baguette.

(The sandwiches can be made 4 hours ahead. Wrap well with plastic wrap and refrigerate.).

For Basil Pesto:.

In a blender, pulse the basil, pine nuts, garlic, 1/2 teaspoon of salt, and 1/4 teaspoon of pepper until finely chopped.

With the blender still running, gradually add enough oil to form a smooth and thick consistency.

Transfer the pesto to a medium bowl and stir in 1/2 cup of cheese.

Season the pesto with more salt and pepper, to taste.

(The pesto can be made 2 days ahead. Cover and refrigerate.)

Yields 1 cup and takes about 10 minutes to prepare.
